Apple must open iPadOS to sideloading within 6 months, EU says
(arstechnica.com)
This is a most excellent place for technology news and articles.
There is no real loophole though. Apple latched on to some part of the Act to justify what they are doing and play for time, while pretending the rest of the Act does not exist. The Act says in no uncertain terms that Apple is not allowed to self-preference - meaning that the alternative app stores must have as much exposure and placement on their platform as their own.
This is not the issue here. The problem is that everybody has to pay through their nose to get the priviledge to publish on an alternate marketplace or be an alternate marketplace.
